Unknown Water Investigation

Unknown Water Investigation

We propose a solution to the problem of being unable to continue the business due to low cost-effectiveness with three keywords!

Constant measures against water infiltration are shifting towards addressing the risks associated with sediment intrusion into pipelines, surrounding cavity formation, and factors leading to road subsidence due to large amounts of infiltrated water. Our company proposes solutions to the problem of being unable to continue operations due to the low cost-effectiveness of unidentified water measures, using three key concepts. Additionally, we offer a package of measurement instruments that meet the requirements and specifications of the investigation, along with support services leveraging Pentaf's expertise, providing economic efficiency and convenience tailored to your needs. 【Approach to Improving Revenue Yield】 ■ Unidentified water deductions ■ Prioritizing opportunity management and risk avoidance ■ Proactive reduction of other unidentified water *For more details, please refer to the PDF materials or feel free to contact us.

Natural origin heavy metal pollution soil insolubilizing agent (RE)

Natural origin heavy metal pollution soil insolubilizing agent (RE)

Safe solidification treatment technology for effectively utilizing construction-generated contaminated soil as construction materials: 'Solidification agent for naturally derived heavy metal contaminated soil using gypsum powder and scallop shells.'

Natural origin heavy metal contamination soil immobilization agent (RE) is an immobilization agent for naturally occurring heavy metal contaminated soil generated at construction sites such as tunnels, rivers, roads, and dams. It is a calcium-based immobilization agent primarily composed of scallop shells and gypsum powder. By adding this immobilization agent (soluble) to the contaminated soil, a reaction layer with a high concentration of calcium is formed on the surface of the soil particles (a site that promotes the immobilization reaction). This reaction layer efficiently immobilizes the heavy metals and suppresses their leaching from the contaminated soil particles.

Activity Project Manta

Activity Project Manta

Collect valuable data on manta rays, which have rarely been studied, and cooperate in building a foundation for long-term monitoring of their habitat.

Looking to the future, manta rays could become an excellent indicator species for monitoring environmental changes in the world's oceans and coral reefs, due to their global distribution and easily recognizable appearance. Global warming has caused significant changes in the state of the Earth's oceans. All changes, including shifts in sea temperature, ocean current patterns, and ocean acidification, could have dramatic effects on the distribution, migration, and behavior of manta rays, as well as on the coral reefs that support their lives. Investigating the relationship between manta ray distribution and migration and large-scale oceanic changes will help researchers monitor and assess the health of the oceans on our planet.

Soil contamination survey [Providing highly accurate and reliable investigation and analysis]

Soil contamination survey [Providing highly accurate and reliable investigation and analysis]

We provide highly accurate and reliable soil contamination surveys!

Under the Soil Contamination Countermeasures Act (Soil Contamination Act), owners of land that was a factory or business site related to the use of specified harmful substances that have been discontinued must have the soil contamination status of that land investigated by a designated investigation agency and report the results to the governor of the prefecture. Additionally, some ordinances may have a broader scope of application for soil contamination investigations than the Soil Contamination Countermeasures Act. For example, the Tokyo Metropolitan Environmental Protection Ordinance requires that when a factory or designated work site is discontinued or removed, not only current but also past handled harmful substances must be investigated, and land alterations of 3,000 m² or more are also subject to investigation. Nisshin Environmental Investigation Center is a designated investigation agency and also an environmental measurement certification business, so if the possibility of soil contamination cannot be ruled out based on the investigation of materials, we will provide highly accurate and reliable investigation and analysis in accordance with the legally prescribed methods (official methods). *For details, please request materials or view the PDF data from the download.
